Re: 292 fuel pump ?

Yeah, a C/50 is a whole different beast. My C/10 Stepside was a fleet runner. Possibly CalTrans surplus by the 516 Orange paintjob. Original buyer specified L25 292, M20 [SM465] and 17.5x5.25'' rims with 7.00x17.5 6-ply bias tires. Original diff was 3.73 I think. [Not SPID specified.]
It glided very well until 4/2022 when I got T-Boned Downtown.
Now I may have frame issues.

My 292 is the original engine block, but has been rebuilt [Ca.2005] with .030-over pistons, 8:1 compression , 1.84 Intake valves, Clifford headers, Offy intake, Edel 1404 4-BBL Carb, HEI. SM465, 12-Bolt Corp rear @3.73. Don't have Posi right now. I had it removed from my T-Boned rearend and will get it reinstalled after I straighten out the frame or steering situation. Bought it used in June 1973.

On those few occasions, I've driven a rental or studio box truck with the split axle shift, the driver had to pull the shift splitter on the stick at the right time. A trick I never quite got, since it wasn't my daily driver.

A couple of years ago, when my Stepside died Downtown on the way in to work, I thought it was the Fuel Pump. After towing home, I R&R-ed the pump. That wasn't the right gripe. My HEI Module had burned out. Changed that, and it was fine.
I kept my known-good, old school fuel pump in the new box for the inevitable event later. I've been thru almost the exact same ''Fuel Pump Adventure'' as Richard J describes -- nearly word for word -- with the Fuel Pump on the 350 SBC in my '71 GMC Jimmy.
